Abstract
Methods for producing substantially single phase yttrium phosphate which exhibits the xenotime crystal structure are disclosed. The methods can be practiced without the use of high temperatures (e.g., the methods can be practiced at temperatures less than 1000° C.). The resulting yttrium phosphate can be in the form of particles which comprise interwoven strands of crystals of yttrium phosphate and/or nanoparticles prepared from such particles.
